LANDINGLADDER FOR SHIPS.

Specification of Letters Patent.

Application filed July 2, 1912.

Patented July 8, 1913.

Serial No. 707,387.

To all whom it may concern Be it known that I, Josnrirr S. Dnanwoon, acitizen of the United States, residing at Sault Ste. Marie, in thecounty of Chippewa, State of Michigan, have invented certain new anduseful Improvements in Landing- Ladders for Ships; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappcrtains to make and use the same.

This invention relates to improvements in landing devices, and hasparticular reference to a device in the nature of a gang plank forlanding a man to catch a line from a ship, at a pier or wharf, which islower than the side rail of the ship.

The principal object of the invention is to provide a simple device ofthis character which may be moved from one part of the ship to anotherand quickly and easily adjusted to suit the relative heights of the pierand rail.

Another object is to provide a simple device of this character which maybe folded to occupy a minimum amount of space.

In the drawings: Figure 1 is a sectional view of a ships side and a piershowing my invention in use, Fig. 2 is a top plan View of the same, Fig.3 is a side elevation of the device, in open position, Fig. 4 is avertical longitudinal sectional view of the device in folded position,Fig. 5 is a vertical transverse sectional view on the line 5-5 of Fig.4, and Fig. 6 is a vertical transverse sectional View on the line 6-6 ofFig. 4:.

Referring particularly to the drawings, my device comprises a truckincluding the longitudinal side bars 10 and the cross brace bars 11,suitable fastenings 12 being secured to the lower faces of the sidebars, in which is mounted an axle 18 carrying Wheels 14: for supportingthe truck.

Slidable longitudinally on the frame of the truck, and held by means ofthe strap hooks 15 is the ladder section 16. At one end of this laddersection and journaled in the ends of the side rails is a Winding drum17, one end of the shaft having a ratchet wheel 18 engaged by a pivotedpawl 19 mounted on the adjacent side rails. Secured to the under facesof the other ends of the side rails of the ladder section 16 are thestraps 20 which are bent outwardly as at 21 the other end of the saidstrap being secured to the end of the adjacent rails and provided with aloop 22, said loop being adapted to be disposed in register withsimilarly formed loops 5213 on the ends of the straps 24; secured to theside rails of a second ladder section 25, said section being disposed ontop of the section 16, a pin 20 being passed through said loop andforming a head for the upper ladder section. The ladder 25 has the crossboards which fill the spaces between the rings, and provides a gangplank.

Near the outer end of the upper ladder section, are cords 27, whichextend rearwardly and. are secured to the hefore-mentioned winding drum.Mounted in the truck frame and journaled in the sides thereof is asecond winding drum 28 having cords 29 wound thereon and secured attheir other end to one end of the ladder section 16, so that uponturning the drum the section 16 may be shifted along the truck to anyclesired position. In one end of each of the side bars of the truck, andat the upper side thereof, is formed a notch or cutaway portion 28, saidnotches being adapted to engage on the side rails of the ship when thedevice is in use.

In using the device the truck is run up to the side of the ship, andpositioned so that the side rails of the ship will engage within thenotches. The ladder section 16 is moved along the truck so that it hangsvertically at the ships side, when the other section of the ladder isswung on its pivot to a hori zontal position so that its outer end restson the pier or dock. The lineman passes from the ship down the laddersection 16, and then walks to the pier on the ladder section 25, thecords 9.7 :iorming hand rails for the gang plank.

What is claimed is:

1. In a landing device for ships, a wheeled truck, a ladder slidable onthe truck, means on the ladder for ei'igagement with the rail of a ship,a second ladder hinged to the first ladder, and adapted for engagementwith a wharf, pier, or the like, means carried by the truck for movingthe first-named ladder on the truck, and means also carried by the firstladder for moving the second ladder toward and away from the wharf,pier, or the like.

9. In a landing device for ships, a wheeled truck, a ladder slidable onthe truck, means on the ladder for engagement with the rail of a ship, asecond ladder hinged to the moving the second ladder toward and awayfirst ladder and adapted for engagement from the Wharf, pier or thelike. 10 With a Wharf, pier, or the like, a ratchet In testimonywhereof, I afiiX my signa- Winding drum on the truck, a cable conture inpresence of two Witnesses.

nected to the drum and the slidable ladder, JOSEPH S. DEARWOOD. aratchet Winding drum on the slidable lad- Witnesses:
